I have a Gigabyte P55W V4 Notebook. My monitor has been having problems for a little while and originally worked when on low brightness and flickered when on a higher brightness, so what I did was kept the monitor of my laptop dim and used a second monitor as my primary one. Now my monitor only works when it's plugged in (it mostly was before, so this may have always been the case) and no longer flickers. Would anyone know what the problem maybe and how I might be able to fix it?
